Suggestions? Sure- here's my particular use-case which highlight the reasons why I would need to modify VPS's admin behavior-
I am using this for panoramic images that I create. So they are much wider than they are tall. This means that in thumbnail-list view the default preview images have very little height to them, making it more difficult to see what they are. I would need to at least double the present width in order to make the images easier to identify.
Also in "list view"- one can add columns to the right to include field data such as name, title etc. In my case, I use three columns of data- the image "TITLE" ( short unique ID's ~10 char), a relatively short (~20 char) category, and a proper NAME (~70+ char). When I include these fields, the added columns are presently evenly spaced. Resulting in a much wider column than necessary for the TITLE, a wider column than is necessary for the CATEGORY, and a column that is too small for the NAME (causing it to wrap). Perhaps a way to designate percentage widths for these columns would be a great addition?
